Tutorial first step

Regarding my posting on the hugin-ptx (hugin and other free panoramic software) list,
for the moment I have decided to make a start on this panotools wiki. I expect to find out
how serious the recommendation of 150kB max upload size is. In principle I would prefer
not to scale down the images I wish to use for illustration.

With the nice new feature of exposure correction in hugin0.7beta one should start soon to write new advice on how to set the camera when photographing a panorama scene. Maybe fixed aperture?

Instead I made a start with Dust Removal with Flatfield recycling text and images of mine,
consider it a test of the features here in the panotools wiki but being more useful than just
a sandbox exercise. -- Klaus 20:24, 2 December 2007 (CET)

Welcome! If you need special features or simply help on how to do something, feel free to ask! --Erik Krause 22:11, 10 December 2007 (CET)

Photos for panoramic images using new hugin version

The usual recommendations hold like

rotate camera around non-parallax point

rest your camera or use a tripod, possibly with panorama head

Newer recommendations would be

better do photos with slightly more than 50% overlap

helps the exposure and vignetting correction

no gap if one photo is spoiled

do NOT use the camera panoramic mode

you risk to have several photos with blown highlights

little control over a number of features

you possibly want to set the distance manually

use fixed aperture (question)??

one vignetting correction can be used

one flatfield for dust removal

from own experience

set the focus to manual

know of several cases where the odd photo of a series would not focus, spoiling all, high risk with featureless panorama parts or non-representative distance in mid photo

if your camera is dust-prone, take a photo of clear sky (could be processed into a flatfield)

For a cylindrical panoramic projection (less than 360deg), cover a wider horizontal range than you plan for the panoramic image, as the barrel shape projection shapes tend to limit the vertical field-of-view in the corners.

With moving objects, clouds or walking persons, try to rotate against the flow in order to avoid duplication.
